Second Place (IMAGE) American Institute of Biological Sciences Caption Heather Krumholtz, from the University of Florida - Whitney Laboratory for Marine Bioscience, won second place by showing postdoctoral associate Dr. Jessica Alice Farrell extracting environmental DNA or eDNA from hundreds of sand samples collected from Florida’s sea turtle nesting beaches. From just a few grains of sand, the Duffy Lab is able to do their research without ever needing to sight or interact with the endangered animals themselves. Credit Heather Krumholtz.
